HUB-BLATE FOB LOCOMOTIVE DRIVING-WHEELS.

Patented April 27, 1909.

Application filed October 24, 1908. Serial No. 459,378.

To all whom it may concern:

Be it known that I, Fiinniiioi( ll. Siii'rii, a citizen oll the UnitedStates, residing at Pittsburg, in the county of Crawford and Stateoliansas, have invented a new and usel'ul liub-tlate l'or LocomotiveDriving- \\.'hcels, ol' which the following is a specilieiition. l

This invention relates to rail-way locomotives and-more particular] tomeans for taking up any lateral or side p ay ofthe drivng .vlwels-ol thelocomotive incident to the pas .re ol the latter over rough unevenrails. The ebiect ol' the invention is to rovide an annular platearranged to fit in t e hub ol' the driving wheel and adapted tobemagainst the driving box or bearing thereb to prevent lateral play ofsaid driving whee A further object is to provide a hub plate or liner,the latter being movable into engagement with the driving box oi*bearing by the pressure of a lubricant introduced at the rear of saidhub plate.

A still further object ol" the invention is gcnerallyto improve thisclass of devices so as to increase their utility, durability andelleieney.

Further objects and advantages will appear in the following description,it being understood Y that various changes in form, proportionsand.minor details of construelion may be resorted to within the scope ol theappended claims. Y

.ln the accompanying drawings forming a part ol this specificationlfigure l is a plan view ol' a pai-tion ol' a locomotive driving wheel'pim ided with a hub pla tc constructed in. :recordarme with niyinvention. a longitudinal sei-tional view of the saine. l'vig. taria-d,-liig. l a perspective view of one el" the peeking rings detached, and-Y-l `ig. l5 il` Sil' hub 'ph'.ic detached.

Similar `numerals ol' reference ind- 'ate cori responding parts in allol' the figures ol' the l rawings.

'lhe impr-f fed hub plate forming the subject matter ol the presentinvention is prinveifpally designedv lor attaclnueut to the drivp nigwheel et a loconu'itive, and bv way ol' .l f i nlnstratnni is shown mconnection with sueli l a driving wheel, in which 5 designates the wheelkeyed on the shalt (i, and the driving box or bearing which may be ot'the usual con@ rue-tion.

Fig. 2 is I a plan View of the hub plate dear view ol the packingringpot the The inner face of the hub 5 is bored out to form an annularchamber S for the reception of the hub ring or liner S), the outer faceel" said liub plate being extended laterally beyond the inner face ofthe h ub for engagement with a bearing ring 1l). The hub plate 9 isi'ovided with an annular groove 11, in

`whicll is seated a split packing ring 12 which latter is designed tobear against the interior wall of the chamber S so as to insure etightfit between the parts. The chamber S is disposed concmt'rie with theaxle 6 and is s aced from the lutter to form an annular l ange 13havinga groove 14 formed therein and `1n which is seated a packing ring15, the latter being adapted to bear against the adfaeent wall of thehub plate, as shown.

i`Xtending laterally from the inner face oi' the hub plate 9 are aseries of ins 16 :irranged to enter corresponding y shaped sockets 17formed in the rear wall of the chamber 8 so as to hold the hub latelstationary on the driving wheel and t ius cause the hub 'late to rotatewith said driving Wheel anilhixle (i.

Formed in the hub of the driving wheel between two ol the adjacentspokes 1S is an opening 19,'the walls of which are threaded lor thereception of the correspondirigly threaded end of a 'lilling plug ortube 20|, there being an aperture 21 iii the hub oi' the driving wheeland forming a source ol coininunioation between the cln'iniber 8 and theinterior ol' the filling plug or receptacle 20 so as to permit theintroduction ol' a quantity l ole grease or other lubricant at the rearof the l hub plate. 'The grease or lubricant in the filling plug 2() islcd to the rear ol' the hub e plate by a plunger 22 engaging theinteriorly l threaded walls olI the. member 2() so that by rotating saidplunger, the lubricant within the tube will be i'oreibly ejected in the.space. between the rear l'ace ol' the hub liner or plate Sl and the rearwall ol the chamber S, thereby to inove said hub plate into engageinentwith the bearing ring 1() and thus l take up any lateral side play ofthe driving wheel incident to the passage ol' the locomo- I tive overrough uneven rails. y

Atiention is here called to the. fact that the llange 23 formed by theseating groove l l is provided with :t plurality ol' relatively smallperl'ora.'ions` '.211 through which fthe grease or other lubricant isled to the rear ot' ilie expansible ring l2 so that when tlie ..plnngcr22 is actuated to press the hub plate lll) #IOT Y s... ,..alilanaJDLilwila! P orlliner against the "bearing 10, a por? tion of the grease orlubricant romthe tube 20 Willpasal through the .apertures 24 vand thusexpand the ring '12. fand assist in venting independent movementk 'of.the plate relatively to the hub ofthevvheel.

An annular V shaped groove'25'is formed in the rear Wall ofthe chamber8, said annu- .lar groove intersecting the :mouth'of the passage 21 andserving to eplxally distribute'the lu ricant l`or grease on t e rearvWall ofthe Y chamber 8 and in position'to lubricat the parts. It willthus be seen that when the plunger 22 is actuated the hub plate or ring9 will bear against the bearing ring of the `driving box, while theexpansible ring 12 will frictionally enga e the interior Wall ofof thehub late thereby to forcethe latter Y corresponding sockets 1n the hubof the against the earing box.

2. The combination With a' locomotive` driving Wheel having an annularseating.

chamber formed in the inner face thereof and provided with an openingcommunicating With said-chamber, of a bearing box, a hub plate seated insaid chamber, and means for mtroducing a lubricant under pressurethrough said opening at the rear of the hub plate, thereby to force thelatter in engage.- ment With the bearing box.

3. The combination with a locomotive driving Wheel having an annularseating chamber formed in the inner face thereof and proviled With anopening communicating Withsaid chamber, of a bearing box, a hublate'seate'd in said chamber, pins extending aterally from the-hub plateand fitting in drawingwheel, and meansfor introducin a lubricant underpressure through sai ope at the rear o the hub plate for forcing the?!atter into engagement with thebearr ing box.

The combination4 with allocomotive driving wheel having an annular seating chamberformed intheinner face thereof and provided with an opening. communicating with saidchamber, o 'a hub plate seated in said chamber and provided with anexpansi- Able packing rin arranged to bear against the interior AWallsit ereof, and a lubricant feediugidevice engaging the opening in the hubof the driving Wheel for feeding lubricant under ressure to the rear ofthe hub plate.

5. T e combination with a locomotive driving Wheel and bearing box, of ahub vplate seated in a chamber formed. in the inner face ofthe hub ofthe driving'wheeland an annular grooveformed therein-and, fdeiin-V a.erforatecl iiange, a packing ring seated insai groove, means forintroducing a -lubrirn .cant under pressure at the rear of the hub'plate for forcing the latterin engagement with the bearingbox, aportion ofthe lubricant beingada -ed tolenter through vthe a ertures inthe ange of the hub plate to t e rear of the packing ring for expandingthe latter. a

6. The combination with la locomotive driving. 'Wheel having an annularseatingV chamber formed therein, the rear Wall lof Which is providedwith a groove, there @being an opening formed in the hub of the Wheel fand communicating With said groove, a hub plate seated in 'the chamber,pins extending aterally from the hub plate and lengaging correspondingsockets formed inthe hub for s acing the hub vplate from the rear- Wallof the chamber, a acking ring surrounding the hub plate andearingagainst the adjacent interior wall of said chamber, a rece tacleseated in the opening in the hub and a' pted to contain a lubricant, anda plunger ov erf ating within the receptacle for forcing lu ricant intothe annular groove, 'a portion of the lubricant being` adapted to passthrough a lertures in the hub plate to the rear of tlib packing ring. rIn testimony that I claim the foregoing as my own, l have hereto aflixedmy signature in the presence of two witnesses.
